Abstract
Disclosed is a composition for concealing graze marks on a transparent glass bottle which comprises: PA0 (A) 100 parts by weight of polydiorganosiloxane having a viscosity of 10 to 100,000 cSt at 25.degree. C. in which 15 to 60 mole percent of an organic group bonded to a silicon atom is an organic group selected from the group consisting of a phenyl group, an aralkyl group and an alkyl group having carbon atoms of 6 or more, PA0 (B) 1 to 100 parts by weight of film-forming polyorganosiloxane comprising: PA1 (1) two or more straight-chain diorganosiloxane portion constituted by 10 or more diorganosiloxane units, and PA1 (2) one or two or more cross-linking portion or portions formed by a reaction of an amino group bonded to a silicon atom through at least one carbon atom and zero or at least one nitrogen atom bonded indirectly to a silicon atom, with an epoxy group bonded to an other silicon atom through at least one carbon atom and zero or at least one oxygen atom bonded indirectly to a silicon atom, wherein the proportional ratio of Part (2) in Component (B) is 0.1 to 30 % by weight, PA0 (C) 1 to 30 % by weight of a cationic surfactant or a surfactant mixture in which a part of t…
